3.6 SP Ramp Set Up Group
Introduction
Set Point Ramp, Set Point Programs and Set Point Rates can be configured in this group.
A single Setpoint Ramp [SP RAMP] can be configured to occur between the current local
setpoint and a final local setpoint over a time interval of from 1 to 255 minutes.
A Set Point Rate [SPRATE] lets you configure a specific rate of change for any local
setpoint change.
A single Set Point Program [SP PROG] with up to 20 segments can be configured.
For more information on Set Point Rate, Ramp and Programming, see Sections 4.27
through 4.30.
You can start and stop the ram
p/program using the
RUN/HOLD key.
PV Hot Start is a configurable feature and means that, at initialization, the setpoint is set
to the current PV value and the Ramp or Rate or Program then starts from this value.
